This document reports back from the DDI 3 workshop “Using DDI 3.0 to Support Preservation, Management, Access and Dissemination Systems for Social Science Data” held at the Schloss Dagstuhl in Germany in November 2007. It intends to present the DDI standard to repository managers, data librarians and data managers and provide background information to help them to examine how the DDI fits with developments in their institutional repositories for research-generated data. The report discusses the appropriateness of using the different DDI versions to address the requirements of research data in IRs. It brings together some of the key questions of the DataShare project with regards to access management, linking to other materials and versioning of datasets.
